15. Astronomers use different types of telescopes to observe different parts of the
electromagnetic spectrum. This allows astronomers to study objects in space. Some
electromagnetic waves are blocked by Earth's atmosphere, making it difficult for
astronomers to focus the energy into a viewable image. Instead of actually viewing
the energy, astronomers have learned to view the interactions of the energy with
the atmosphere. These faint interactions with the atmosphere allow them to study
highly energetic objects such as pulsars and black holes.

If the waves that are being observed have a frequency of 1022, what type of wave is
being observed?

A.gamma rays
B.ultraviolet
C.microwave
D.radio waves

Answers

Answer 1

It’s radio waves because it’s found at the longest wavelengths on the electromagnet spectrum

Answer 2

At the frequency of 1022, the radio waves will be observed.

What is an electromagnetic spectrum?

The complete range of electromagnetic radiation, classified by frequency or wavelength. Despite the fact that all electromagnetic waves have a wide range of frequencies, wavelengths, and photon energies, they all move at the speed of light in a vacuum.

The range of all electromagnetic radiation is represented by the electromagnetic spectrum, which also includes numerous subranges, also known as portions, such as visible light and ultraviolet radiation.

The various parts have different names based on variations in the emission, transmission, and absorption of the corresponding waves as well as on the various practical uses for which they are put to use.

At the frequency of 1022, the wave observed will be a radio wave.

How are both electromagnetic and mechanical waves used when people communicate with each other?

Answers

Unlike mechanical waves, which require matter, electromagnetic waves can travel through empty space, as well as through liquids, solids, and gases. There are many similarities between light waves and mechanical waves. They can both be measured by their amplitude, wavelength, and frequency.

Electromagnetic and mechanical waves used when people communicate with each other, this done by an antenna(sender & receiver)

What is antenna ?

An antenna is a metallic structure that produce or/and receives electromagnetic waves it is available in different shapes. There are different types of antennas which are Short Dipole antenna, Dipole antenna, Loop antenna, Monopole antenna.

when input of the Dipole antenna is connected to the electric signals having certain frequency. Due to change in the electric signal, there is fluctuation in polarity of dipoles in dipole antenna and that change in the dipole produces electromagnetic wave.

when electromagnetic wave is received by the dipole antenna, dipoles in the antenna get affected by electromagnetic waves, dipoles fluctuate at frequency of received electric signals and produces electric signals of same frequency as electromagnetic wave.

Sound wave is mechanical wave. sound wave is converted in electric signals by using microphone, it gets amplified and given to to input of the antenna(Transmitter). This antenna converts Electric signal into electromagnetic wave. This converted electromagnetic wave is received by another antenna(receiver). this antenna converts electromagnetic wave into electric signals, this signals are amplified and given it to the speaker.

Hence this is how people use electromagnetic and mechanical waves for communication.

The graph represents the percentages of salt water and fresh water on Earth. What is the percentage of salt water?

1. 3 percent
2. 50 percent
3. 97 percent
4. 100 percent

Answers

Answer:

97.

Explanation:

Though the exact number is 96.5, we can round it up since its 5. When rounding by 10, 5 or more rounds up and 4 or less rounds down. So rounding up of 96.5 is 97. 3)

The percentage of salt water is 97 percent on Earth. Hence, option (3) is correct.

What is water distribution on Earth?

Saline seawater makes up the majority of the water in the atmosphere and on the surface of the Earth, with fresh water making up less than 1% of the total. The majority of the water on Earth is saline or salt water, with an average salinity of 35 ‰ (or 3.5%, or around 34 grams of salts in 1 kg of saltwater), though this fluctuates slightly depending on the amount of runoff absorbed from nearby land.

Over 97% of the water on Earth comes from the oceans and marginal seas, saline groundwater, and water from saline closed lakes, however no closed lake holds a large amount of water on a global scale. Except when evaluating water quality in arid places, saline groundwater is rarely taken into account.

Answers

Answer: 1- A diagram showing the forces acting on the object.

2- The force vector describes a specific amount of force and its direction. You need both value and direction to have a vector.

3- A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it.

4- I don’t know

5- When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces

6- By applying an unbalanced force, you can change the motion of an object. Unbalanced forces can make an object at rest start moving, make a moving object stop, or change the direction and speed of the object.

7- If the forces on an object are unbalanced, this is what happens: a stationary object starts to move in the direction of the resultant force.

8- Imbalance or unequal force

9- The result is no motion. Balanced forces can cancel each other out. Any time there is a balanced force, the object does not move.

10- net force is the vector sum of all the forces that act upon an object.

RESTATE THESE

Explanation:

RESTATE!!!!

1. To demonstrate all the forces acting on an object.
2. They tell us about the direction of the force and the magnitude of the force relative to the other forces acting.
3. Larger vector arrows demonstrate a larger magnitude of a certain quantity. Vice versa.
4. In which direction are all of the forces in the diagram?
5. It means that there is no net force on the object - the forces sum up to zero. Forces are balanced if they are equivalent and in opposite directions.
6. Unbalanced forces ALWAYS CAUSE ACCELERATION (speeding up / slowing down). If an unbalanced/net force acts on an object, that object will ALWAYS accelerate in that direction for as long as the force is applied.
7. It means that there IS a net force acting on the object, aka the sum of the forces is greater than zero.
8. Net forces. Symbolized by Fnet or Greek letter Sigma before the F.
9. Absolutely no CHANGE IN motion. This is Newton’s First Law of Motion - basically all objects continue in their state of motion unless acted on by an unbalanced force. Note if an object is already moving and balanced forces act on it, it will continue moving. No change in motion.
10. It is the vector sum of the forces acting on an object in a certain direction.

How does gravity cause the solar system to move within the galaxy?

Answers

The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.

Gravity causes the solar system to move within the galaxy without any

issues and it is known as the strong bond that holds together entire galaxies

which includes the sun, moon, planets etc.

This keeps the planet revolving around the sun and ensures there is no

deviation from the line followed from the onset. If there is a deviation and

planets end up crashing into one another then the result will be very

disastrous and would lead to mass loss of lives.

Gravity also ensures that different planets and countries have a very different

type of climate due to the relative exposure of the planets/areas to the sun.
